Description
Technical field
The present invention relates to a kind of be used to dispose of sewage reinforced vertical flow filter bed, belong to environment-friendly engineering and water-treatment technology field.
Background technology
Main at present source of pollution control and the ecological restoring method of adopting administered sewage, and artificial filter bed is one of important scientific method.Artificial filter bed is a kind of sewage disposal technology of continuous evolution, and ultimate principle is: the specific plant of plantation on certain filler, when effluent stream is crossed artificial filter bed; Filter through sandstone, soil; Through the multiple microbial activities of aerobic one by one in the matrix fill layer of sand, anaerobic reaction micro unit and plant rhizosphere, the biochemical degradation deposition reduces Pollutant levels; Water quality is purified, until qualified discharge.Treating processes comprises biochemical reaction, like decomposition and anabolism, plant absorbing; Physical-chemical reaction is as precipitating absorption etc.
Utilize artificial filter bed that artificial filter bed of free-water level or the artificial filter bed of undercurrent type are adopted in the sewerage ecological reparation usually.The artificial filter bed of undercurrent type according to sewage above that mobile direction difference more refinement be divided into horizontal flow filter bed and vertical flow filter bed two kinds.The artificial filter bed hydraulic load of free-water level is low, and sewage treating efficiency is not high, needs a large amount of waters and soil with the assurance decontamination effect improving, and in a single day the pollution of area source input is arranged, and its decontamination effect improving is very not obvious.The artificial filter bed of horizontal flow filter bed and free-water level is compared, and hydraulic load and pollution load are big, and is good to organism such as BOD, COD and heavy metal removal effect.But the horizontal flow filter bed is compared with vertical flow filter bed, its shortcoming be denitrogenation, dephosphorization effect a little less than.
Vertical filter bed refers to that sewage is surperficial to filter bed from the intermittent water distribution of settling tank, and downward then vertically flow by gravity is a kind of high efficient technology in the artificial filter bed, effectively handles all kinds of sewage in conjunction with physical filtering and biochemical reaction.Matrix fill in the filter bed is that microbial bacterial provides a very adapt circumstance; Organonitrogen is an ammonia nitrogen through the ammonification mineralising; Under aerobic condition, ammonia nitrogen changes nitrate salt and nitrite into through nitrification, then under the condition of anaerobism and organic carbon source; Partly be reduced to nitrogen through denitrification, discharge into the atmosphere.P contained compound mainly is reaction in matrix fill, enrichment, deposition, thereby from sewage, removes.In the sewage infitration process, through aerobic, the anaerobic reaction micro unit in the filler layer of sand, the biochemical degradation deposition, Pollutant levels reduce.
There are deficiencies such as assembling inconvenience, water distribution are even inadequately, filter bed corner water distribution is insufficient, building structure is stable inadequately, floor area of building waste in the existing vertical flow filter bed square structure that is.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of reinforced vertical flow filter bed, the problem that is intended to effectively to solve square vertical flow filter bed inconvenience assembling with exist the dead angle to cause problems such as processing is perfect inadequately.
The object of the invention is realized through following technical scheme:
Reinforced vertical flow filter bed, characteristics are: said filter bed is the circular configuration that two semicircles constitute, and the filter bed bottom is equipped with anti seepage membrane, is covered with header on the said anti seepage membrane, and said header two ends connect ventpipe; The inner filling substrate of said filter bed, filter bed surface serike; Two semicircle upper edge filter bed diametric(al)s at filter bed are distributed with the water distribution person in charge respectively, are responsible for the water distribution branch pipe that is connected with water distribution and are arranged to external irradiation by the filter bed center with semicircle shape.
Further, above-mentioned is reinforced vertical flow filter bed, and wherein, said matrix is made up of ecological filler processing layer, transition layer and layer of displacement, and said ecological filler processing layer is the upper strata, and said transition layer is the middle layer, and said layer of displacement is a lower floor.
Further, above-mentioned is reinforced vertical flow filter bed, and wherein, the body of wall of said filter bed is made up of the customization aluminum alloy materials of being convenient to assemble, peripheral by the environment-friendly materials veneer.
Further, above-mentioned is reinforced vertical flow filter bed, wherein, is disposed with gravel bed and lime compacting bed course between said filter bed bottom and the anti seepage membrane.
Again further, above-mentioned is reinforced vertical flow filter bed, and wherein, said header is arranged to external irradiation with the filter bed center, and header connects ventpipe near filter bed body of wall one end.
Again further, above-mentioned is reinforced vertical flow filter bed, and wherein, it is 50/m that the surface plantation of said filter bed has short cattail and reed, iris and Canna generalis Bailey, the planting density of short cattail and reed
2, the planting density of iris is 15 strains/m
2, the planting density of Canna generalis Bailey is 15 strains/m
